This 30-gallon vessel was likely intended to hold whiskey, so your family lore stands to reason. Further supporting the claim? Stamps on the stoneware jug identify its origin as Paducah, Kentucky--a state with a moonshine-distilling past--and its maker as John Andrew Bauer. Since Bauer relocated his business to Los Angeles by 1910 (changing the name from Paducah Pottery to J.A. Bauer Pottery Company), your heirloom hails from the ceramist's early history.
